Get the most from your vehicle with routine maintenance
Routine maintenance is the best way to help ensure you get the performance, dependability, long life and
resale value you expect from your vehicle. This is exactly why we’ve put together the Scheduled
Maintenance Guide. It outlines the services required to properly maintain your vehicle and when they
should be performed. The focus is on maintaining your vehicle while it’s running great, which goes a long
way toward preventing major repairs and expenses later.
Here are a few suggestions to help you get started on the road to routine maintenance:
•Familiarize yourself with your vehicle by going through yourOwner’s Guide
•Take a few minutes to review this handy Scheduled Maintenance Guide
•Make it a habit to use this guide to record scheduled maintenance
•Consider your Ford and Lincoln Mercury Dealership for all your vehicle’s needs
Protect your warranty!
Routine maintenance is not only the best way to help keep your vehicle running great, it’s also the best
way to protect your warranty. While maintenance and repair services may be performed by you or
by any automotive service provider you choose, it is your responsibility to see that all scheduled maintenance
is performed and that the materials used meet Ford Engineering specifications. Failure to perform
scheduled maintenance specified in this guide will invalidate warranty coverage on parts affected by the
lack of maintenance. We can’t stress enough how important it is to keep records of all maintenance. This guide
will help you do just that. Ford Motor Company will not deny a warranty claim simply because there is
no documentation.However, damage or failures due to neglect or a lack of proper maintenance
are not covered under warranty.
Keeping maintenance records is easy with the Scheduled Maintenance
Guide
It’s important to document the maintenance of your vehicle. Every time you bring your vehicle in for
scheduled maintenance, be sure to present this guide and certify the work. Also record the date of service,
mileage at the time of service, and attach your receipt. This will make record keeping easy and,
should your vehicle ever require warranty coverage, you will have all the documentation to show you’ve
properly maintained it.
Maintenance Interval
Ford Motor Company establishes recommended maintenance intervals based upon engineering testing to
determine the most appropriate mileage to perform the various maintenance services. This protects your vehicle
at the lowest overall cost to you. Ford Motor Company recommends that you not deviate from the
maintenance schedules presented in this Scheduled Maintenance Guide.

Determine which maintenance schedule to follow
It’s important to follow the maintenance schedule that most closely mirrors your driving habits and the
conditions under which you drive. For this reason, the Scheduled Maintenance Guide is divided into two basic
maintenance schedules: the
Normal Schedule(further segmented intoTrucks, Fullsize Vans & SUVsandCars & CUVs) andSpecial Operating Conditions
Determining which maintenance schedule is right for you is easy. For the most part, do you drive your
Ford, Lincoln or Mercury vehicle under typical, everyday conditions? If so, follow theNormal Schedule Trucks,
Fullsize Vans & SUVs,orNormal Schedule Cars & CUVs.
Special Operating Conditions
However, if one or more of the Special Operating Conditions outlined below better describes how you
typically operate your vehicle, you will need to perform some maintenance services more often than the Normal
Schedule recommends.
•Towing a trailer or carrying heavy loads
•Extensive idling and/or driving at low-speeds for long distances
•Driving in dusty conditions
•Off-road operation
•Use of E85 fuel 50% of the time or greater (flex fuel vehicles only)
Important:For further details and information regarding these Special Operating Conditions see page 41.
Maximum Oil Change Interval
❑Normal Schedule: 7,500 miles or 6 months, whichever occurs first.❑Special Operating Conditions: 5,000 miles, 6 months, or 200 hours of engine operation, whichever occurs first
see appropriate schedule on page 41.
Motorcraft Premium Gold Engine Coolant
❑6 years or 105,000 miles - change Premium Gold coolant (whichever comes first)❑After initial change - change Premium Gold coolant every 3 years or 45,000 miles (see page 48)

If you’re unsure which maintenance schedule to follow, ask your Ford and Lincoln Mercury Dealership, or
visit the Maintenance area of www.genuineservice.com.
Oils, Fluids and Flushing
In many cases, fluid discoloration is a normal operating characteristic and, by itself, does not necessarily
indicate a concern or that the fluid needs to be changed. However, discolored fluids that also show signs of
overheating and/or foreign material contamination should be inspected immediately by a qualified
expert such as the factory-trained technicians at your Ford or Lincoln Mercury Dealership. Your vehicle’s oils
and fluids should be changed at the specified intervals or in conjunction with a repair. Flushing is a
viable way to change fluid for many vehicle sub-systems during scheduled maintenance. It is critical that
systems are flushed only with new fluid that is the same as that required to fill and operate the system, or
using a Ford-approved flushing chemical.
Chemicals and Additives
Non-Ford approved chemicals or additives are not required for factory recommended maintenance. In fact,
Ford Motor Company recommends against the use of such additive products unless specifically
recommended by Ford for a particular application.
Your vehicle is very sophisticated and built with multiple complex performance systems. Every manufacturer
develops these systems using different specifications and performance features. That’s why it’s
important to rely on your Ford or Lincoln Mercury dealership to properly diagnose and repair your vehicle.
When planning your maintenance services, consider your Ford or Lincoln Mercury dealership for all your
vehicle’s needs.

ENGINE IDLE HOUR METER (IF EQUIPPED):
Your vehicle may be equipped with an idle meter to indicate how much time the vehicle is idling in P (Park)
or N (Neutral). The meter is incorporated with the vehicle odometer. Depressing the odometer-reset button
once will display the trip odometer (miles followed by a “T” for trip odometer). Depressing the odometer-reset
button a second time will display the idle meter (hours followed by an “H” for hours). The idle meter
only accumulates time when the vehicle is in P (Park) or N (Neutral). Displayed time is cumulative for the
vehicle.It cannot be reset to zero.
Police/Fleet vehicles often experience long periods of idling,
during which engine oil will continue to break down but mileage is not accumulated on the odometer.
To assist fleet managers in maintaining proper oil change intervals, the idle meter will help determine when
an oil change is required. For every hour that the vehicle idles, it has accumulated the equivalent of
approximately 33 miles of driving. Using the combination of the vehicle odometer and idle meter allows
the fleet manager to better determine when the oil needs to be changed
Engine idle hour meter calculation:
Idle hours x 33 = miles equivalency
Miles driven + miles equivalency = oil change interval
Example:When the odometer has accumulated 3,000 miles and the idle meter shows 61 hours, a
5,000 mile oil change interval will have been reached: 3,000 road miles + (61 idle hours x 33 miles/idle
hour) = 5,013 miles.

In addition, there are several exceptions to the Normal Schedule. They are listed below:
Normal Vehicle Axle Maintenance
❑Rear axles and power take off (PTO) units containing synthetic lubricant and light duty trucks equipped with
Ford-design axles are lubricated for life. These lubricants are not to be checked or changed unless a leak is suspected,
service is required or the axle assembly has been submerged in water. The axle and PTO lubricant should be
changed anytime the axle and PTO have been submerged in water. During extended trailer tow operation above 70°F
ambient and wide open throttle for extended periods above 45 mph, non-synthetic rear axle lubricants
should be replaced every 3,000 miles or 3 months, whichever occurs first. The 3,000 mile lube change interval
may be waived if the axle was filled with 75W140 synthetic gear lubricant meeting Ford specification
WSL-M2C192-A, part number F1TZ-19580-B or equivalent. Add friction modifier C8AZ-19B546-A (EST-M2C118-A)
or equivalent for complete refill of Traction-Lok rear axles (see
Owner’s Guidefor quantity). The axle
lubricant should be changed anytime an axle has been submerged in water.
Police/Taxi/Livery Vehicle Axle Maintenance
❑Replace rear axle lubricant every 100,000 miles. Rear axle lubricant change may be waived if the axle was
filled with 75W140 synthetic gear lubricant meeting Ford specification WSL-M2C192-A, part number FITZ-19580-B
or equivalent. Add four ounces of additive friction modifier C8AZ-19B546-A (EST-M2C118-A) or equivalent for
complete refill of Traction-Lok rear axles. The axle lubricant should be changed anytime the axle has been submerged
in water.
E–450 and F–450/550 Axle Maintenance
❑Replace rear axle lubricant every 100,000 miles under normal driving conditions on all E–450 and
F–450/550 applications. For E–450 and F–450/550 vehicles operated at or near maximum Gross Vehicle
Weights, the rear axle lubricant should be replaced every 50,000 miles. In addition, this 50,000 mile schedule
should be observed when the vehicles are operated under the Special Operating Conditions, where noted, on
page 41.
California Fuel Filter Replacement
❑If vehicle is registered in California, the California Air Resources Board has determined that the failure to
perform this maintenance item will not nullify the emission warranty or limit recall liability prior to the completion
of the vehicle’s useful life. Ford Motor Company, however, urges you to have all recommended maintenance
services performed at the specified intervals and to record all vehicle service.
